Specification of Letters Patent.

Patented April 23, 1907.

Application iiled June 19,1906. Serial No. 322,365.

Be it known that l, `W1LL1AM F. OVER- MYER, a citizen oit the United States, residing at Beechwood, in the county of Amite and State of Mississippi, have invented certain new and useful Improvements in Gins, oil which the following is a specilication.

My invention relates to an improvement in gins, and it consists in the constructions, combinations and arrangements herein described and claimed. y

An object of my invention is to provide a compact form of gin having a high capacity, and especially adapted for reginning cotton seed in preparing the seed for manufacture into cotton seed products.

A further object oi my invention is to provide a simple and durable form of gin, operating with a minimum of power, and constructed to completely delint the cotton seeds, thereby avoiding waste or loss of the cotton fibre.

In the accompanying drawings, iorn'iing a part of this application and in which similar reference symbols indicate corresponding parts in the several views: Figure l is a central, vertical, sectional view, illustrating one embodiment of my invention, and Fig. 2 is a detail view of the lower rotating set of saws.

Referring' to the drawings, l .indicates suitable supports `tor a. casing comprising side walls 2, a rear wall 3, and. a top 4L. Shafts 5 and suitably ournale d in the casing, carry, respectively, an upper and a lower of gin saws 7 and S at the liront portion ol' the casing. A shaft 9, j ournaled in the casing, carries a brush cylinder 1() for removing the lint from both sets of rotatable saws and discharging it through a lint llue 11 baille plates, or wind guards, 12, 123 and 141- being arranged in proximity to the periphery of the brush cylinder'. A mote board 19 is adjustably supported in guides 2O on the casing, and carries a del'lector 21 for separating heavier impurities, such as dirt, sand, etc., from the lint prior to its discharge into the lint flue 1].. This construction permits ad justment of the de'llector 21 to produce an efficient separation ot' heavier impurities -from the lint for all grades oi seed cotton.

The material is supplied. to the gin by an adjustable feeding means comprising a hopper 15, a breast board 16 and a seed board 17. A grating comprising bars 22 is carried by the adjustable feeding means in position to extend. between the several saws of the upper and lower sets 7 and b 5 the several bars being' set sul'liciently close together to prevent passage olu cotton seed tlwrebetween. The i'eeding means is zuljustably secured to the casing, as by a hingel joint 1S, and l have shown a rack lever L3 pivotcd at 24 to the casing and engaging a lug 25 on the iceding means :For locking the latter in its several adjusted positions about its pivotal support 1S. The lower set olx saws S are positioned to constitute the bottom oit a roll chamber 26 in which the material is balled or rolled, by the action ol the gin saws thereon. The several saws of the lower set 8 are spaced apart by spacing .members 2T a sullicient distance to permit the entrance of cotton seeds therebetween, and the seed board 17 is provided with an adjusting screw 2S for enabling it to be adjusted in close proximity to the perijihery ol thc lower set oil saws S. i

ln the operaton of my invention, the material is fed through the hopper 15, and the gin saws strip the lint from the cotton seeds in the roll chamber 26 and carry it past the grating 22 to the brush cylinder 10. The brush cylinder cleans the lint 'from the saws in the usual manner and discharges it against the mote board 19 and into the lint llue 11; the rapid motion of the brush cylinder acting to produce a current across the mote board and through the lint illuc. During such discharge of the lint trom the brush cylinder, any heavy impurities mixed with the lint will be dellected dowinvardly by the adjustable dellector 2l thus separating it from the lint which will surface of the mote board and discharged. into the lint liuc.

The cotton seeds, a'lter being dclinted in the roll chamber 26 drop between the several saws of the set S constituting the bottom ol said chamber, and are diseharged vlrom the gin past the `front surfaces ol the spacing members 27. This constriuftion prevents the discharge of any partially delinted seeds from the roll chamber, since the saws S will engage any lint remaining on partially stripped seeds and prevent the latter' from dropping within the small spaces between the several saws.

The ad j ustablc vireding means carrying the grating 22, provides a convenient means tor varying the action of the gin saws on the cotton within the roll chamber 26, thereby enabling the gin to be set, or adjusted, for opcrbe drawn by the air current across the upper IOO ating ellieiently on all eliaraoters and grades of material. v

l liave illustrated and described a preferred and satisfactory construction, but, obviously, changes eould te made witliin the spirit and seope of my invention.

Having tlius described my invention, what l claim as new and desire to seeure by Letters Patent is i. ln an apparatus of 'the eliaraeter described, the combination of two independent` sets Ol' rotatable gin-saws, a grating extending between the several saws orp said. two sets, an adjustable feeding means vfor supplying material to said saws, and means lfor simultaneously adjusting' the posi-ion ot said grating relative to tlie said' two sets et saws and 'tor varying the @apar-ity of the 'feeding means.

2. ln an apparatus o' tbe oliaraster deseribed, tne e-oinbinatiml of two independent sets of rotatable gin-saws, a grating extending between tlie several saws oi'l said two sets, an adj ustalzle feeding means for supplying material to said saws, means for simultaneously adjusting the position of said grating relative to the said two sets of saws and for varying the Capacity of the feeding means, a seed board, and means for independently adjusting said seed board relative to the saws.

3. In an apparatus of the Character described, tlie combination of two independent sets of rotatable gin saws, a grating extending between the several saws of said two sets, an adjustable feeding means for supplying material to said saws, said grating being seeured to tlie movable part of said adjustable feeding means and adapted t0 move simultaneously therewith, means for simultaneously adjusting tbe position of said grating with respect to said two sets of saws, and for varying the oapatity of tbe feeding means, a seed board, and means Jfor adjusting said seed board relative to tbe saws.

ln testimony whereof l a'liix my signature in presence of two witnesses.

WILLIAM F. OVERMYER.
